Red oak

Quercus rubra


60 feet tall, this photo was taken in Late November


The active ingredients in oak bark are tannin and quercin. Quercin is similar in effect to salicin and is used along with bioflavinoids to strengthen the capillaries and veins. Oak bark also contains ample amounts of calcium, manganese, potassium and magnesium. Its primary therapeutic properties are astringent and antiseptic. A few of oak’s other properties—haemostatic (arrests internal bleeding), febrifuge (reduces fever), diuretic, anti-emetic (relieves malarial-type fevers and chills), and anti-venomous (antidote for poisonous plants, insects and snake bites.)
